[Peter Boesman]

The Clements update also splits Gray-browed Wren
'Mantaro Wren' is there (seperately) listed as undescribed

This is probably the best approach until genetic data become available.

At present vocalizations and morphology point in different directions:

• vocally it is very different from schulenbergi and quite similar to Inca Wren (see my note)
• morphologically it is 'plain-tailed'

I guess that sukahujan from Taliabu falls under Turdus schlegelii AKA Wallacean Island Thrush?

sukahujan is a ssp of Turdus deningeri (Moluccan Island-Thrush) in the recent Clements spreadsheet.

Jul 3: post split of Sandhill Grasswren from Rufous Grasswren

 

[Markus Lagerqvist]

Jul 4 Post lump of Salvadori's Eremomela with Yellow-bellied Eremomela.

 

[Xenospiza]

sukahujan is a ssp of Turdus deningeri (Moluccan Island-Thrush) in the recent Clements spreadsheet.

It wasn't investigated, so I guess it should be left incertae sedis. Biogeographically it would seem more likely to fall into schlegelii.

Jul 5 Post lump of Germain's Swiftlet with Edible-nest Swiftlet.

One down for most,

 

[TomDerutter]

Does this mean Swiftlets in Singapore become identifiable?

 

[opisska]

After a long time finally something I actually had

 

[Andy Adcock]

Jul 5 Post lump of Buff-chested Babbler with Rufous-fronted Babbler.

To quote that 60's hit 'there's a whole lotta a lumpin goin on'.

Jul 5 Post lump of Buff-chested Babbler with Rufous-fronted Babbler.

Cyanoderma ambiguum is sister to C. ruficeps according to Cai & al. (2018 ; 2020)

Cyanoderma ambiguum is sister to C. ruficeps according to Cai & al. (2018 ; 2020)

The lump is ambiguum with rufifrons, not ruficeps

 

[Jim LeNomenclatoriste]

The lump is ambiguum with rufifrons, not ruficeps

But this lump with rufifrons is impossible if ambiguum is sister to ruficeps

 

[Mysticete]

Probably can look at that Clements update to get a sense of what else is coming down the pipeline soon. The Redpoll lump is on that list and that one is going to hit probably near everyone here I would guess.

 

[Andy Adcock]

I'd be surprised if some recent splits don't get re-lumped, we've already seen it with IIRC, Shrike Babblers, Drongos and Lesser Whitethoats.

Some of the East/West or North/South splits might be particularly, vulnerable to re-lumping IMHO, Northern Mealy Amazon with Southern Mealy Amazon being just one, recent example.

I could imagine East/West splits in Africa being particularly vulnerable, slightly less so, (Sahara) North/South.

Some seabird activity might also be expected?

But this lump with rufifrons is impossible if ambiguum is sister to ruficeps

So the logic should be that either all three get lumped or that if only one of them, then it has to be ambiguum and ruficeps?

Am I understanding that correctly?

No, no lump, for me in any case. Ambiguum is probably a valid species according to recent studies

Jul 5 Post re-lump of Sulawesi and Seram Swiftlets with Halmahera (Moluccan) Swiftlet.

This is the geographical zone that was foremost in my mind in post #2755

In published trees, rufifrons was actually basal to ([ambiguum, ruficeps], pyrrhops).

(Cai et al 2018 analyzed two data sets -- one which was the entire supermatrix they had built, and which had all 4 spp of this group; the other in which they had removed some taxa that they regarded as rogue, including rufifrons. Without rufifrons, they recovered a topology ([ambiguum, ruficeps], pyrrhops) which was very strongly supported (internal node with MLBS = 100); with rufifrons, the support to all the internal nodes in the group was low (MLBS = 69; BPP ≃ 0.7). To me, this suggests a problem with the data.)

A subspecies re-arrangement that I think has affected my list and might be of interest to others:

Collared Scops Owl

Otus lettia

Add subspecies cnephaeus.

ADD

Subspecies cnephaeus, previously synonymized with the nominate subspecies of Otus lempiji, is reassigned to Otus lettia based on vocalizations (Wu & Rheindt 2023).

I presume cnephaeus covers at least everything on the Thai-Malay peninsula?
